    Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 sorry, mail to that recipient is not accepted (#5.7.1) (state 14).

    That does not look like an Exchange error. Have you pointed your MX records at your server?

      In nslookup, enter set q=mx to tell it to list MX records, and then enter your domain name. If your server's public IP is not listed, then as Sembee pointed out, you will need to check your DNS.
